This is how the new ford 6.7L diesel should had come from the factory

well i really am mediocre...

Seems like after the Job 1 trucks ford fixed all the minor problems. And once you get rid of the DPF then it's a very reliable engine. As long as you don't hammer the dog shit out of it. I got 50k miles on my truck and 45k of those miles have been tuned. Not a single problem out of it. But hey it's the worst design engine.

I didn't know 50k miles was a "tried and true" engine?

6.4's are definitely maintenance hogs and minus the shitty radiators aren't too bad. Fuel economy was just piss poor though. Wasn't around long enough after the 6.7's came out to properly judge them.

6.4's are definitely maintenance hogs and minus the shitty radiators, thermostats, front covers, EGR coolers, high pressure fuel pumps, multiple PCM recal's aren't too bad. Fuel economy was just THE SUCK. Wasn't around long enough after the 6.7's came out to properly judge them.

bwahaha

At what mileage are you seeing those problems listed above?

I sold a 08 that other than radiator and almost consistent dpf clog problems was pretty trouble free up until 97k miles when I traded it in.

I've got a 09 on the road now that just hit 90k and it has been in for one repair involving a radiator hose. Only trip to dealer since new.

I have seen several HPFP failures but almost all of those were due to owners not changing the filter. I know two people who had it happen. One was at 30k miles and it had never had a fuel filter, the other at 80k miles and it had the underhood filter replaced once and the framerail filter was oem.

6.4's get great mileage when you delete all the bullshit

[appelingogt]

whats it get w/o the bull shit? Gotta be better than 12mpg

Mine is bullshit free and still haven't broke 16. My 6.0 would do that at 80 mph.

My best tank with bullshit on was 15.8, the exact same as without.

My worst tank not towing was 11.7. Worst tank after is a little over 13.


Overall I did see an improvement, just not what I expected. I expected highway to be much better with 3.55 gears.

whose tuning are you running?

[jdgregory84]

bwahaha

All the shit you listed are 6.0 problems. Not 6.4. How do I know? By the amount of money I made off of them....which is a LOT. Seriously, other than Bio-fuel, fuel regulator, injectors(like any diesel)...

Bio-fuel is the big bitch. During cold weather, bio-fuel gels up, and clogs up the fuel system. What a bitch. Warranty doesn't cover that BTW.

EDIT: They had a couple of PCM problems. Usually it was because of aftermarket chips though. The PCM's in new vehicles don't like being fucked with improperly.

Damn dude I get over 20 mpg per fill up. I do mostly highway driving. And thats even with 35's.

Go to some diesel sites and you see a lot of job 1 6.4's with numerous problems before they hit 50k miles. But I know for a diesel engine that 50k miles isn't shit. Just saying that he said it's the worst design ever which means I should have problems all the time if that was true. International told ford that the 6.4 will be the most reliable engine they produce for ford. But only time will tell. By this time next year I will have over 100k miles and I bet my truck still won't have anything wrong with it in that time.


As long as I don't run the dog piss out of it with the big tunes.

There is no way my truck will ever touch 20. I don't think if it were two wheel drive it could do it.

I put the same set up on a friends 08 and his mileage is about the same as mine, but he has 3.73 gears.

We a both on stock 20" wheels with stock 34" tires. He has a 38' fifth wheel and he did pick up almost 1 mpg hwy towing.

My two best tanks are all highway, which is 15.8 mpg. I have right over 12k miles on it and it will be a year old end of next month. About to change the oil a fuel filters.

I don't need one. I have a great relationship with a ford place I've been dealing with for years.
